Diversity in micromineral distribution within the body of ornamental fish species Ghent University
This study was conducted to compare micromineral homeostasis across ornamental fish species. Ten different species (n = 3, total = 30) of live ornamental fish were randomly sampled from one big aquarium in a pet store in Belgium. All fish samples were dissected manually for the collection of targeted tissues. The tissue samples were ashed by microwave oven, and the extract was analyzed for copper (Cu), iron (Fe), and Zinc (Zn) by inductively ...
The Fish fauna of the Kundelungu National Park (KNP/ DR Congo): diversity and conservation KU Leuven
The Kundelungu National Park (KNP) is situated in the south-eastern part of the Democratic Republic of the Congo. It was created in 1970 and at first only included a core zone (CZ) at high altitude (~ 1300-1700m asl) on the Kundelungu Plateau (KP). In 1975, it was expanded with an annex zone (AZ) towards lower altitude areas (~ 800-1100m asl) situated along the Middle Lufira valley. The AZ is connected to the Upemba National Park (UNP) through ...
Environmental and spatial patterns of freshwater fish diversity in Flanders KU Leuven
Riverine biodiversity is deteriorating rapidly as a result of multiple interacting anthropogenic pressures. Freshwater species are subject to physico-chemical pollution originating from various sources (e.g. agriculture, industries, households), hydro-morphological alterations (e.g. construction of dams, river calibration), and the introduction of invasive species (e.g. topmouth gudgeon, Chinese mitten crab, round goby in Flanders). Conservation ...
The fish diversity of the river systems of the Kahuzi Biega National Park (East DRC) KU Leuven
The fish diversity of the Lowa and Ulindi systems, both right bank tributaries of the Upper Congo (Lualaba), has been underexplored and poorly known. As a result, the diversity and distribution of the fish species of these systems remained almost terra incognita. These two systems drain the Kahuzi-Biega National Park (KBNP). The absence of scientific fish collections from this park hinders the integration of the fish fauna from the park into the ...
Geographic isolation and climate govern the functional diversity of native fish communities in European drainage basins University of Antwerp
Aim In times of biodiversity crisis, it is extremely important to understand diversity gradients. In particular, the study of the diversity of ecological functions is a key issue for the management of ecosystem integrity. Here we identify areas of low functional diversity of the native fish fauna in European drainage basins and we determine the relative importance of three underlying mechanisms: environmental filtering, geographic isolation and ...
Partitioning global patterns of freshwater fish beta diversity reveals contrasting signatures of past climate changes University of Antwerp
Here, we employ an additive partitioning framework to disentangle the contribution of spatial turnover and nestedness to beta diversity patterns in the global freshwater fish fauna. We find that spatial turnover and nestedness differ geographically in their contribution to freshwater fish beta diversity, a pattern that results from contrasting influences of Quaternary climate changes. Differences in fish faunas characterized by nestedness are ...
Sampling errors and variability in video transects for assessment of reef fish assemblage structure and diversity Ghent University
Video monitoring is a rapidly evolving tool in aquatic ecological research because of its non-destructive ability to assess fish assemblages. Nevertheless, methodological considerations of video monitoring techniques are often overlooked, especially in more complex sampling designs, causing inefficient data collection, processing, and interpretation. In this study, we discuss how video transect sampling designs could be assessed and how the ...
Diversity of planktonic fish larvae along a latitudinal gradient in the Eastern Atlantic Ocean estimated through DNA barcodes Vrije Universiteit Brussel
Mid-trophic pelagic fish are essential components of marine ecosystems because they represent the link between plankton and higher predators. Moreover, they are the basis of the most important fisheries resources; for example, in African waters. In this study, we have sampled pelagic fish larvae in the Eastern Atlantic Ocean along a latitudinal gradient between 37◦N and 2◦S. We have employed Bongo nets for plankton sampling and sorted visually ...
